I saw an article that Google is also collecting data from Google Drive. While they say they don't use it for AI at the moment, their TOS also doesn't rule it out in the future. So not only is Google scraping data from websites, but also from personal data of its users. That would mean they have a lot of training data to work with. I guess with AI threatening the search engine's use case, Google has now started moving in different industries. It's like the sleeping giant has finally woken up.
